citizen *of' thei United States, residing at Chillicothe, inthe county of-Livingston and Stateof Missouri, have invented certain new and useful Improvements in Smoke-Stack Attachments, of which the following is a specification", reference beinghad to" the accompanying drawings.

This invention relates improvements in smoke stack attachments and more particularly to a device of this character for dissipating the smoke, the

main object of the present invention being the provision of an attachm'entfor locomotives or stationary engine smoke stacks,

V whereby a quantity of air is mixed with Another object of'the present the smoke issuing from the stack so as to' dilute the smoke and cause-the same to quickly permeate the atmosphere.

the invention consists in the novel features of constructlon, combinatlon and arrangement of parts as willvbe hereinafter referred to and more particularly pointed out in the specification and claim.

extending above the upper end of said stack, is a bell-shapedcasingS having its opposite ends'open and which is arranged in spaced relation withithe smoke stackso of the casing to the;top. The lower end of the casing 3 terminates above the lower end,

Extending'alongslde the locomotive body t 1, is an air pipe 7, theoutere'nd of which is 1 provided with "a plurality of branchpipes 8 adapted to eXtendinto the lower end of the 1 casing 3 to discharge air or steam therein.

The inner end of the pipe 7 extends into withavalve10,th'e i'nner end-of said pipe bemg' adapted to communicate with the compressed, air supply tank or with the steam chamber of the locomotive boiler,

whereby upon the actuation of the valve 10,

air will be forced into the'casing 3 and up-' wardly out through the opening,thus miX- ing with the smoke as it passes from the upper end of the stack-2.

the cab 9 of the'locomotiveand is provided I f It was be understood that while I h ve I described the reduced neck of the bellshaped casing as preferably smaller, in

diameter than the stack, it will be understood that the sides .of this opening. will vary according to the class of work the engine is required to perform and also the character of the" engine upon which the de- It'willbe noted that the upper ends of the branch pipes 8 which extend upwardly fromthe main pipe 7 are arranged in spaced I relation with the loweropen endof thecas ing; 3, sov that should steam be forced through the pipe 7, it will carry into the' casing '3, air from the exterior thereof, the i air being" forced inwardly and upwardly by I the steam- :From this it will be apparent; that I have provided a simple and durable" device for dissipating the smoke which can be applied to a'locomotive smoke stack or a stationary engine smoke stack, whereby air I 'will be -miXed' with thejsmoke as it'lissuesfrom the stack and cause the smoke to, more thoroughly permeate the air than by having the smo'ke'issuing directly from the stack The device, as..herein. shown and :dea scribed, is extremely simple in construction, 7

can be quickly and readily applied 'to'a locomotive engine and, at the same time, can be manufactured and placed upon the market at a comparatively low cost.

.Wh-ile I have shown and described the preferred form of my invention, it will be 7 obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practlce, w thout sacrificing any of the novel features or departing from the scope of the invention, as defined by the ap aended claim.

aving thus described this invention,

What I claim is e In comblnation with a smoke stack, a casing surrounding the upper end of sa1d stack Copies of this patent may be obtained for and in predetermined spaced relation thereto, the opposite ends of said-"casing being open, the upper end of the casingrt'erminat- 'ing above the stack'and the loWer end of the casing terminating above the lower end of the stack, and means for forcing a draft through the casing, said "means comprising JOHN T.
